Guaripolo, the children's favorite character of 31 minutos, directs "Radio Guaripolo", from where he broadcasts the program "Guaripolo's Midnight Telephone Pranks", in which in the wee hours of the morning he makes prank calls to a few, for the delight of few others. The show features new instrumentations of the show's well-known songs, emulating the bluesy feel of 1960s Chicago.
